Cleaning method for cartridge filter

Dear all,
I hope you and your family are safe during the panademic.
I have a question about cartridge filter 0,22mcm (polyethersulfone) - PES. We used this for filter solution contain 1% HPMC and got problem caused by premature binding of filter and HPMC. This lead to the filtration take longer than normal and the cartrigde filter no longer reuse.
Anyone have experience about the filtration of cellulose solution, can give me an advice for cleaning method to help reduce this phenomenon?.
Thank in advance.
P/s: We used hot/cold method for soluble HPMC, but with water cooling system in double layers pot, we only reduce temperature approx 35°C while fitter.
